The number of potential landing sites for the Mars 2020 rover has been narrowed down to three, from a list of eight, following a conference of scientists last week. The top three landing sites that were selected were in Northeast Syrtis Major, Jezero Crater, and the Columbia Hills in Gusev Crater. The landing sites in the Columbia Hills and Syrtis Major display evidence of geothermal and mineral hot springs that could have been conducive to hosting primitive life, and Jerezo Crater shows evidence that it was once a lake of liquid water.

Northeast Syrtis Major was once influenced by volcanic activity that warmed underground sources of water ice that reached the surface as mineral hot springs. These hot springs could have hosted microbial life similar to organisms that have been found in similar environments on Earth. The area also displays layered terrain that holds a record of the interactions between water and minerals throughout early Martian history.

On ancient Mars, water-carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit shows that some of these sediments have minerals that indicate chemical alteration by water. Here in Jezero Crater delta, sediments contain clays and carbonates. The image combines information from two instruments on NASAs Mars Reconnaissance Orbiter: the Compact Reconnaissance Imaging Spectrometer for Mars and the Context Camera.

Jezero Crater is an example of the on-again/off-again nature of liquid water on Mars. There is evidence that the crater was filled and drained of water on at least two different occasions around 3.5 billion years ago. Channels can be seen leading into and out of the crater, and there is spectral evidence that suggests clay minerals were formed and deposited as sediment in the lake. These clay minerals are similar to the sediments being examined by the Curiosityrover in Gale Crater and could have played host to microbial life.

This approximate true-color image taken by the Mars Exploration Rover Spirit shows a rock outcrop dubbed Longhorn, and behind it, the sweeping plains of Gusev Crater. On the horizon, the rim of Gusev Crater is clearly visible. The view is to the south of the rovers current position. The image consists of four frames taken by the 750-, 530- and 430-nanometer filters of Spirits panoramic camera on sol 210 (August 5, 2004).

The Columbia Hills were famously explored by the Mars Exploration Rover (MER) Spirit between 20032010 where it discovered evidence the area once hosted a hot spring with liquid water similar in composition to hot springs found on Earth. If selected as the final landing site, the Mars 2020 rover would further inspect hot spring sediments to investigate their potential to host life. Mars 2020 will also revisit an outcrop that was visited by Spirit which in a recent analysis by scientists was thought to resemble a fossilized mat of microbial organisms that have been found in similar hot spring sediments on Earth. This particular outcrop represents the strongest evidence for fossilized life to have been found on the Martian surface to date.

The Mars 2020 rover is designed to address several key scientific objectives and the effectiveness of the potential landing sites to meet those objectives factored into the selection of the final three landing sites. Those objectives are the following:

Additionally, the Mars 2020 landing site must also meet the following criteria:

The three finalist landing sites were selected from an original list of 8 which also included Eberswalde Crater, Holden Crater, Mawrth Vallis, Nili Fossae, and Southwest Melas Chasma. The rover is currently under development and is similar in construction and function to Curiosity and is targeted to launch during the summer of 2020 and landing on Mars in early 2021.

Try To Survive A Doomed Space Flight In ‘Homebound’ – Tom’s Hardware

Quixel, a studio most recognized for its hand in developing graphics technologies for game franchises such as Battlefield, Destiny, Doom, Starcraft, and Dark Souls, has announced that its debut VR title is now available on Steam for the Oculus Rift and HTC Vive.

Have you ever wondered what it would be like to plummet to the earth in a failing spacecraft? Homebound is your (one-way) ticket to exactly that, as you become a lone astronaut struggling to survive a disaster as your ship hurdles out of control towards the planet.

As an increasingly sinister-sounding computer AI guides you through the ship, youll start with menial tasks that allow you to explore the spacecraft and experience the joy of weightlessness (and ruffled potato chips). The mood will start to get creepy as you discover more of your environment, with the trailer implying that there is more to your mission than just being a good astronaut. Youll inevitably press a stereotypical big red button, at which point things take an intense turn for the worse, as explosions tear through the ship and send it crashing towards Earth. (Get it? Homebound!)

Homebound was created using Quixel Suite, the texturing toolkit used in many of the aforementioned AAA game titles. The engine purportedly offers increased visual fidelity, with the company claiming its Megascans technology delivers the most believable surfaces to date in VR. Whether that's true or not, you'll need significant horsepower under the hood to meet Homebound's recommended specs, which calls for a GTX 980ti and an Intel Core i7 processor. Windows 10 is also preferred, with the spec list suggesting DirectX 12 as the recommended API.

You can download Homebound now from Steam, for a limited-time price of $7. The promotion ends on February 23, when the game returns to its full price of $9.

Indian rocket set to place 104 satellites in orbit – Spaceflight Now

Indias Polar Satellite Launch Vehicle is scheduled to fire into orbit early Wednesday with 104 satellites on-board, setting a record for the largest flock of spacecraft ever launched on a single rocket.

Most of the payloads cocooned inside the PSLVs nose shroud are as small as a toaster oven, set to join commercial fleets tasked with daily imaging of the Earth and the collection of weather data to improve forecast models.

The 145-foot-tall (44-meter), four-stage PSLV is set for liftoff at 0358 GMT Wednesday (10:58 p.m. EST Tuesday) from the Satish Dhawan Space Center, Indias launch base on the coast of the Bay of Bengal.

The launch is scheduled for 9:28 a.m. local time in India.

The prime passenger aboard the rocket is the Indian Space Research Organizations Cartosat 2D environmental satellite, a 1,574-pound (714-kilogram) observatory to help analysts update maps, plan urban and rural infrastructure, monitor coastlines and track water usage.

Deployment pods mounted on the PSLVs upper stage also hold 96 CubeSats made by Planet and Spire Global, two San Francisco companies adding to commercial satellite constellations.

Planets 88 spacecraft awaiting blastoff will nearly double the number of satellites the company has launched since its founding in 2010. The majority of Planets orbiting camera platforms have been ejected from the International Space Station in orbits that do not fly over the entire globe, while the satellites going up from India will launch into polar orbit, enabling worldwide coverage.

The small 10.3-pound (4.7-kilogram) CubeSats, nicknamed Doves, carry a sharp-eyed camera, extendable solar panels, and high-speed data transmitters to beam images to antennas around the world. Each flock of Planet satellites debuts upgraded technology, with the suite of spacecraft launching Wednesday named Flock 3p.

This is the fifteenth time Planet is launching Dove satellites; and it will be our biggest launch to date, Planet wrote in an update on its website earlier this month. Combined with the 12 satellites of Flock 2p operating in a similar orbit, this launch will enable Planets 100 satellite line scanner constellation of Doves. With our RapidEye satellites and Doves operating in other orbits, Planet will be imaging the entire Earth daily.

Planets satellites do not have the high resolution of larger, more expensive Earth observatories like those owned and operated by DigitalGlobe but their large numbers allow customers to refresh views of a specific location on the ground more often.

The launch of 88 Dove satellites comes less than two weeks after Planet announced the acquisition of Terra Bella from Google, which has a constellation of seven higher-resolution spacecraft capable of recording high-definition video during passes over ground targets.

Eight 10.1-pound (4.6-kilogram) Lemur satellites owned by Spire Global are also set for launch Wednesday.

The shoebox-sized craft carry GPS radio occultation antennas, using satellite navigation signals passed through Earths atmosphere to derive temperature and humidity profiles that can be fed into numerical forecast models.

Spires satellites also track ships out of range of terrestrial receivers.

The company has launched a total of 21 CubeSats, some of which have ended their missions.

Spire won a $370,000 contract from NOAA in September to supply pilot data for the weather agency to determine the informations usefulness. If the pilot program proves fruitful, NOAA could place an order for more weather data from Spire and other commercial satellite startups to supplement measurements from government-owned satellites.

Seattle-based Spaceflight Services booked the Spire satellites aboard Indias PSLV mission, along with an Israeli CubeSat named BGUSat developed by Israel Aerospace Industries and Ben Gurion University. BGUSat, conceived as an educational research project, will take pictures of clouds from space and measure atmospheric background radiation.

The other international payloads stowed for Wednesdays launch are four CubeSats for institutes and companies in the Netherlands, Switzerland, the United Arab Emirates and Kazakhstan.

ThePiezo Electric Assisted Smart Satellite Structure, or PEASSS, project will validate a new class of composite structures and power systems for future space missions.

Backed by European Union research and development funding, the PEASS mission will help develop, manufacture, test and qualify smart structures which combine composite panels, piezoelectric materials, and next-generation sensors, for autonomously improved pointing accuracy and power generation in space, officials wrote on the mission website.

Smart structures will enable fine angle control, thermal and vibration compensation, improving all types of future Earth observations, such as environmental and planetary mapping, border and regional imaging, according to mission officials.

The 6.6-pound (3-kilogram) PEASSS spacecraft was developed by a consortium of Dutch companies and scientific institutes.

The Swiss-headquartered company SpacePharma is launching its first satellite Wednesday. Named DIDO 2, the 9.3-pound (4.2-kilogram) CubeSat is the first in a line of small spacecraft SpacePharma hopes to send into orbit hosting miniature microgravity research experiments.

The student-built Al-Farabi 1 and Nayif 1 CubeSats from Kazakhstan and the United Arab Emirates, respectively, are also heading to space on the Polar Satellite Launch Vehicle. Al-Farabi 1 will test out a communications system, and Nayif 1 carries an amateur radio transponder.

The 101 international CubeSats are stored inside 25 QuadPacks built by Innovative Solutions in Space, a Dutch firm specializing in arranging rideshare launches for small satellites.

Two Indian nanosatellites, named INS 1A and 1B, round out the 104 spacecraft awaiting blastoff.

INS 1A and 1B, each weighing about 20 pounds (9 kilograms), will demonstrate a new type of camera and gather measurements of Earths atmosphere and the space environment.

No imminent X-37B landing planned – Spaceflight Now

CAPE CANAVERAL The enigmatic X-37B spaceplane, launched into low-Earth orbit on an experimental military mission in 2015, continues to circle the planet despite a flurry of landing rumors.

The X-37 is still on-orbit. The program is conducting a regularly scheduled exercise this week, said Capt. Annmarie Annicelli, media operations officer at the Pentagons Air Force Press Desk.

Internet chatter buzzed in recent days about a potential landing of the stubby-winged spacecraft at the Kennedy Space Centers Shuttle Landing Facility as early as this morning.

But the Pentagon put those rumors to rest with its brief but pointed statement.

The X-37B was launched on May 20, 2015 and spent its 636th day in space today on a classified mission.

This fourth flight of the unmanned and reusable spaceplane program carried at least two payloads on its latest voyage. The military revealed before the ship took off that it was carrying an experimental electric propulsion thruster to be tested in orbit and a pallet to expose sample materials to the space environment.

What else, if anything, the vehicle is carrying in its pickup truck-size cargo bay is unknown.

As of today, the X-37B program has used twin reusable vehicles to amass 2,004 cumulative days in space on four flights since 2010, launching like a satellite atop Atlas 5 rockets and then landing like an airplane.

The three previous flights landed at Vandenberg Air Force Base in California. But the Air Force and builder Boeing have worked to consolidate all X-37B launch and landing operations at the Kennedy Space Center to use the former hangars and runway from the now-retired civilian program.

Photos: Ariane 5 rocket in position for first launch of 2017 – Spaceflight Now

A powerful Ariane 5 rocket rolled out of its vertical assembly hangar to a tropical launch pad on the shores of South America on Monday, and these photos show the booster on the eve of liftoff.

Standing 180 feet (55 meters) tall, the Ariane 5 is scheduled for blastoff Tuesday with the Sky Brasil 1 and Telkom 3S communications satellites. It will be the 91st launch of an Ariane 5 rocket since 1996, and the first of up to seven Ariane 5 flights planned by Arianespace in 2017.

The images below show the Ariane 5 emerging from the final assembly building in French Guiana for the 1.7-mile (2.7-kilometer) journey to the ELA-3 launch zone. Officials also released photos of the rocket after arriving at the launch pad, which sits in a clearing about 2 miles (3 kilometers) from the Atlantic coast.

The rocket is composed of a core stage and upper stage, each consuming cryogenic liquid hydrogen and liquid oxygen propellants, and two side-mounted solid rocket boosters with pre-packed powder fuel.

Scientists narrow list of landing sites for NASA’s next Mars rover – Spaceflight Now

The delta inside Jezero Crater offers one of the best locations on Mars to look for the remains of ancient microbes, according to scientists. Jezero Crater received the most votes during a ranking of potential destinations for NASAs Mars 2020 rover last week.

A rover NASA plans to launch to Mars in 2020 will likely explore one of three locations selected last week by a scientific advisory group, which picked candidate landing sites that were once homes to ancient lakes and hot springs.

Were looking for a site thats ancient around 4 or so billion years old because thats when we think Mars had water flowing and a more clement environment, said Jack Mustard, a professor at Brown University who sits on the Mars landing site selection board. We need to be able to characterize the habitability of that environment and look for preserved biosignatures. And in addition to the science on the ground, we need to find the right samples to return later.

The six-wheeled robot, similar in appearance and capability to NASAs Curiosity rover currently on Mars, will look for signs of past Martian life, assess the habitability of the environment, and measure the chemical, mineral and organic make-up of rocks, with an emphasis on hunting for biosignatures, the natural relics left behind by alien microbes.

Its other chief objectives will be to collect at least 30 test tube-sized core samples for possible retrieval and return to Earth on a future mission, and test a new device to generate oxygen from carbon dioxide in the Martian atmosphere, validating a tool future missions could employ to produce breathable air, water and rocket fuel.

Scientists met last week in California to narrow a list of eight potential destinations selected in 2015. Acting on the advice of the 172 researchers, NASA settled on three finalists Saturday, setting the stage for a final decision by top agency managers in 2018 or 2019.

The robotic mission, officially named Mars 2020 for now, will launch in July 2020 aboard a United Launch Alliance Atlas 5 rocket and reach the red planet in February 2021, descending through the atmosphere with the assistance of a heat shield, parachutes and braking rockets before cables unreel to place the rover on the surface.

The sky crane descent system is based on the technology demonstrated with the landing of Curiosity on Mars in August 2012.

The shortlist of landing sites includes the Columbia Hills, a range of heights in 4-billion-year-old Gusev Crater where NASAs Spirit rover landed in January 2004.

Spirit found evidence that the region had a watery past after climbing from its touchdown point in the basin of Gusev Crater into rounded highlands named for the astronauts who died aboard the shuttle Columbia.

The rover drove 4.8 miles (7.7 kilometers) during its mission, and kept going after one of its wheels stopped turning. The inoperable right-front wheel dragged up white soil the rovers spectrometer determined the material was nearly pure silica and scientists linked the unexpected discovery with the presence of ancient hot springs and steam vents.

Such an environment could have hosted microbes billions of years ago, making it an ideal location to land the Mars 2020 rover, scientists said.

Spirit reached a feature named Home Plate, the remnant of a hydrovolcanic explosion involving three key ingredients for life: heat, energy and water. The Spirit rover, which functioned 25 times longer than its 90-day design life, also found outcrops of carbonate in the Columbia Hills, deposits which scientists say were emplaced during a wetter period of Martian history.

Data gathered by Spirit also indicate Gusev Crater could have periodically flooded and made shallow lakes.

Proponents of the Columbia Hills site also tout the possibility of sending the Mars 2020 rover to inspect Spirit where it bogged down in a sand pit in 2009 and likely froze its internal electronics during a frigid Martian winter. NASA last heard from Spirit in March 2010 and gave up on recovering the mission in May 2011.

Information on Spirits condition could give engineers insight into how extreme temperature swings, dust storms and possible micrometeorites affect hardware like coatings, optics, actuators and cabling on Mars, providing a bonus opportunity for a long duration exposure experiment, scientists said.

This data will aid in design of future surface systems, equipment and structures for both manned and robotic exploration of Mars, scientists wrote in a presentation backing the Columbia Hills site.

Spirit ended its mission before reaching several more geologic features scientists wanted to visit.

The other two potential targets for the Mars 2020 rover are Jezero Crater, home to an ancient river delta, and a region named Northeast Syrtis, a location that appears to be rich in layered clays with some of the oldest terrain found on Mars.

Jezero and Northeast Syrtis about 30 miles (50 kilometers) apart lie at about 18 degrees north latitude. Neither place has been explored on the surface.

Jezero Crater tells a story of the on-again, off-again nature of the wet past of Mars, NASA wrote in a description accompanying the landing site announcement. Water filled and drained away from the crater on at least two occasions. More than 3.5 billion years ago, river channels spilled over the crater wall and created a lake.

Imagery obtained from NASAs Mars Reconnaissance Orbiter show clear evidence of a dried-up river delta that fed a lake. Scientists think the delta deposits, which came from a watershed stretching 4,600 square miles (nearly 12,000 square kilometers), offer one of the best places on Mars to look for preserved organic matter and biomarkers in samples the rover could scoop up and store for return to Earth by a later mission.

Any organic matter that might have been in that [watershed] is going to get concentrated in an area we can explore with a rover, said Tim Goudge, a postdoctoral fellow at the University of Texas at Austin who made the case for Jezero Crater.

That makes it easier to maybe find the needle in the haystack because youre potentially collecting lots of needles in one spot, Goudge said in a Brown University press release.

Once the Jezero lake dried up, water may have continued to flow into the crater, stacking layers of clay minerals that hardened to form sedimentary rock.

Conceivably, microbial life could have lived in Jezero during one or more of these wet times, officials wrote in Saturdays announcement following the science meeting. If so, signs of their remains might be found in lakebed sediments.

Jezero received the most votes during the landing site conclave.

Orbital observations show the nearby Northeast Syrtis site, the second-leading vote-getter, is covered in the remains of an underground hydrothermal system. Supporters of this landing destination point to scattered patches of carbonate, made from interactions between water and the mineral olivine, a process that produces hydrogen molecules, a possible energy source for microbes.

On Earth, we have evidence of these ancient lineages of bacteria that lived off of rocks in the subsurface, feeding off of chemical energy, Mustard said in Browns press release. Here we have that feedstock and there was water, so that makes it really exciting.

The age of some of the exposed rocks at Northeast Syrtis also makes for an attractive target.

The rocks we would touch down on would be 4 billion years old, older than any rocks on Earth, said Mike Bramble, a Brown graduate student who also presented at last weeks landing site meeting. So thats a chance to answer all kinds of questions about the formation of Mars and the formation of planetary surfaces in general.

All three candidate landing sites meet NASAs engineering requirements, providing a safe, relatively flat and boulder-less location for the rover to touch down on the surface.

Scientific concerns will drive mission managers recommendation of one or two primary landing sites at a future meeting. Officials at NASA Headquarters charged with a final decision are expected to endorse one of the top destinations scientists recommend.

Air Force’s X-37B prepares for landing at KSC’s Shuttle Landing Facility – NASASpaceflight.com

February 14, 2017 by Chris Gebhardt

Not even two days after historic launch complex 39A at the Kennedy Space Center was revived by SpaceX following retirement of the Space Shuttle, the historic Shuttle Landing Facility at the Florida spaceport is preparing toonce again host an end of mission landing as the Air Forces X-37B mini spaceplane returns from a near two year mission on orbit.

Kennedy Space Center shines as a multi-user spaceport:

The retirement of the Shuttle fleet left a rather large hole in the Kennedy Space Centers (KSCs) ability to launch and conduct human orbital space operations.

At the conclusion of the historic reusable spaceplane program, NASA vowed to transition KSC from a single-user, single rocket facility into a multi-user, multi rocket spaceport for the 21st century.

The first two steps in that plan were the initiation of reconstruction efforts of pad 39B to prepare it for the ability to launch NASAs Space Launch System rocket for Beyond Earth Orbit missions and the 2014 agreement for a 20-year lease of pad 39A to SpaceX for its Falcon 9 and Falcon Heavy rockets.

With the final Shuttle launch from pad 39A on 8 July 2011, the pad lay dormant as reconstructive efforts took place ahead of this past weekends return of fire and thrust from rocket engines for SpaceXs static fire of the Falcon 9 rocket that will loft the SpX-10 mission to the Space Station later this week.

After Atlantis final launch from Pad A, the vehicle returned for the final landing of the Shuttle program back at the Kennedy Space Center on 21 July 2011 after which the Shuttle Landing Facility (SLF) has not since hosted an End Of Mission (EOM) landing of an orbital mission.

Tomorrow, weather permitting, that will change, and two of the Kennedy Space Centers iconic elements will be back in operation within two days of each other.

With Boeing building and processing its CST-100 capsule inside former OPF Bay 3 as part of NASAs Commercial Crew Transportation services contract and last weeks completion of platform installation in the VAB for SLS stacking operations, the Kennedy Space Center is truly shining as a multi-user spaceport.

Specifically for the Air Force, the ability to use the SLF at Kennedy marks what is hoped to be the first of many uses of the SLF as the primary EOM landing facility for the X-37B which the Air Force hopes to launch, land, and refurbish at KSC and the Cape Canaveral Air Force Station.

In fact, after landing, the X-37B is expected to be towed to OPF-1 for post-flight servicing operations.

OTV-4 Fourth flight for X-37B comes to an end:

The fourth flight of the Air Forces experimental X-37B spacecraft assuming a landing on Monday, 14February 2017 will clock in at 636 days and 22 hours (approximate to its anticipated landing time).

If all goes according to plan, the X-37B will approach the Kennedy Space Center for a landing no early than0800EST (1300 UTC) though this time is approximate and based on unverified orbital tracking observations of the X-37B.

Depending on the specific path the X-37B follows in its entry sequence currently understood to be a descending node entry over portions of the United States and Florida large swathes of Central Florida could be graced with twin sonic booms during the morning commute as the X-37B rather insistently heralds its arrival back home.

The ability for this fourth mission to attempt a return to the runway at Kennedy follows three highly successful, completely autonomous deorbit, entry, and landing sequences of the first three X-37B flights, which all ended with precise touchdowns at the runway at Vandenberg Air Force Base, CA.

OTV-2 and OTV-3 landed without incident following a blown tire that led to minor underbelly damage of the OTV-1 vehicle (which subsequently flew the OTV-3 mission).

With an expected mission duration of just under 637days, the fourth flight of the X-37B program will not be the longest with that distinction going to the OTV-3 flight which lasted 674 days and 22 hours.

Nonetheless, the mission will resoundingly beat the OTV-2 mission duration of 468 days and 14 hours and the OTV-1 mission duration of 224 days and 9 hours.

Moreover, the prolonged duration of the current and previous X-37B missions highlight the secretive nature of the spaceplane, its missions, end its designed orbital lifetime which is currently listed as 270 days something which three of the four missions to date have shattered.

Presently, two X-37Bs are known to exist, with the first flying the OTV-1 and -3 missions and the second flying the OTV-2 and -4 (presumably) missions.

In all, each X-37B is 8.92 m (29 feet 3 inches) in length, has a 4.55 m (14 foot 11 inch) wingspan, has a height of 2.9 m (9 feet 6 inches), and has a maximum lift off weight of 4,990 kg (11,000 lbs).

The vehicles are powered by gallium arsenide solar cells with Lithium-ion batteries and contain a 2.1 x 1.2 meters (7 feet x 4 feet) payload bay.

In preparation for landing at Kennedy, teams practiced landing drills and post-landing safing operations as well as emergency drills at the SLF last week.

The X-37B landing also helps explain the until now curious delay to SpaceXs launch of the SpX-10 resupply mission for the International Space Station which had originally been scheduled for the 14th as well the opening day of the X-37Bs landing attemptsat Kennedy.

When the SpaceX mission was delayed, it was stated that range assets necessary for the return to launch site landing of the Falcon 9 core stage were not available from 14-17 February, while all other range assets necessary for launch were available during that window.

While the secretive nature of the mission precludes any exact knowledge of the ground track the X-37B will take, a descending node reentry over large portions of the United States is the likely option given the landing window for the restricted air space in and around the Kennedy Space Center.

A descending node entry would lead toan earliest possiblelanding at 0800EST at Kennedy, which shouldsee the X-37B put on quite a light show for portions of the United States as it reenters the atmosphere in the early morning darkness before crossing the night-day Terminator and heading for a post-sunrise landing in Florida.

While the landing per the restriction notices originally slated to occur on 14 February, there is now evidence that the USAF has scheduled a back-upopportunity fortomorrow, 15 February.

Nonetheless, the NOTAM and flight restriction zone through 3,000 feet around the SLF extendsfrom 0800-1600L on the 14th meaning a landing is possible at any time in that window when orbital mechanics allow.

Thus, 0800 EST was only the earliest possible landing for Tuesdays attempt.

With no proven orbital ground track for OTV-4 since its maneuver last week, there are only good approximations of its suspected landing time hence the estimate of 0748-0800L for the first possible landing opportunity Tuesday.

Moreover, Tuesday was just theopen day of several landing possibilities as the EasternRange, per SpaceXs slip from today to the 18th, was in conflict from 14-17 Februaryshowing that X-37Bs opportunities to land are over days, not hours.

Additionally, after the 0800 hour passed at Kennedy, the NOTAM that was in effect was officially extended to the 15th, with the same general 0800-1600L restriction times.

On Tuesday, the Pentagon aimed at deflecting the interest in the potential landing, citing it the program was conducting a regularly scheduled exercise. However, the NOTAMs remain in place at the time of the update.

Seven poster sessions and seven studies based on data returned by the New Horizons mission will be presented at the 48th Lunar and Planetary Science Conference, which will be held in The Woodlands, Texas, on March 2024 of this year (2017).

Centered on Pluto and its moons, the Kuiper Belt, and KBOs, the 14 presentations are humorously titled New Horizons Views of Pluto and Charon: So Long, and Thanks for All the Bits.

The posters will be displayed on Tuesday, March 21, at 5:30 p.m. CDT in the Town Center Exhibit Arena, while the papers will be presented on Wednesday, March 22, between 8:30 a.m. and 10 a.m. CDT in the Montgomery Ballroom.

William McKinnon and Adrienn Luspay-Kuti are chairing the paper presentation event.

Data from NASAs New Horizons mission indicates that at least two (and possibly all four) of Plutos small moons may be the result of mergers between still smaller moons. If this discovery is borne out by further analysis, it could provide important new clues to the formation of the Pluto system. Image & Caption Credit: NASA / JHU-APL / SwRI

Poster sessions include the following:

Paper presentations are as follows:

The posters and papers come just after the New Horizons team was awarded the NASA Group Achievement Award, which recognized over 600 people for developing the spacecraft and working on the mission.

Ralph Semmel, director of the Johns Hopkins University Applied Physics Laboratory, emphasized that unlike many other awards given to the mission team, which focused on specific aspects of the mission, this one acknowledged teamwork by the group as a whole.

This team has worked flawlessly for long periods of time, and very few people understand what it takes to do that, said NASA Planetary Science Director Jim Green. That takes dedication; that takes concentration, [and] that takes everything each and every one of you have to have to burn a hole in steel. Thats what puts you above everything else.

Fire returns to flame trench at Apollo-era launch pad in Florida – Spaceflight Now

Credit: William Harwood/CBS News

Nine Merlin engines ignited and throttled up to nearly 2 million pounds of thrust Sunday during a brief hold-down firing of SpaceXs Falcon 9 rocket, sending a plume of smoke out of the flame trench at Kennedy Space Centers historic launch pad 39A as the company preps for a space station cargo mission next weekend.

The Merlin 1D engines on the rockets first stage were programmed to fire for about three-and-a-half seconds, reaching full power with around 1.7 million pounds of thrust as the Falcon 9 booster remained affixed to the seaside launch complex.

Onlookers at Kennedy Space Center reported visible venting of super-chilled liquid oxygen vapors from the rocket leading up to the static fire test, then a white cloud of rocket exhaust rushing out of the north side of the launch pad as the Merlin engines ignited at 4:30 p.m. EST (2130 GMT).

SpaceX confirmed a few minutes later that the static fire was successfully completed, and engineers are reviewing data collected during the test.

Sensors in each engine were to measure many performance parameters during the brief ignition at the launch pad. Hold-down restraints kept the rocket on the ground.

The hotfire test marked the first time a rocket ignited at pad 39A since July 8, 2011, when the final space shuttle mission blasted off there. The launch complex sat dormant for three years until SpaceX signed a 20-year lease to take over the pad in 2014.

The milestone static fire test is a major step leading to SpaceXs first-ever launch from pad 39A scheduled for next Saturday, Feb. 18, with a Dragon supply ship carrying 5,266 pounds (2,389 kilograms) of equipment and experiments to the International Space Station.

If the rocket takes off Feb. 18, the Dragon spacecraft will reach the research lab in orbit Feb. 20.

It will be SpaceXs first resupply launch to the space station since last July, before a Falcon 9 rocket exploded on the Complex 40 launch pad at nearby Cape Canaveral Air Force Station.

The explosion grounded the Falcon 9 rocket for the rest of 2016, and left Complex 40 with significant damage requiring repairs.

Preparations at pad 39A took on a feverish pace in the months since the Sept. 1 explosion at pad 40, which sits on Air Force property a few miles south of pad 39A.

The crucial static fire test doubled as a check of the rockets readiness for flight and the function of the launch pads fueling, telemetry and water deluge systems, all of which were overhauled by SpaceX in recent months.

With the test completed, ground crews will lower the rocket and attach the Dragon cargo freighter for launch next weekend.

Hans Koenigsmann, SpaceXs vice president of flight reliability, said Wednesday that testing of the new ground systems at 39A was nearly complete, allowing managers to move ahead with rollout of the rocket.

This is a huge pad, Koenigsmann said. The runs from the LOX (liquid oxygen) farm and the fuel farm down to the launch head are huge. The transporter-erector is huge. Its like one-and-a-half million pounds of steel, and (it has) so much technology because this thing controls all the interfaces (with the rocket).

The transporter-erector will carry rockets from the hangar up the incline to the pad, then lift the vehicles vertical. The rocket carrier was observed vertical at pad 39A in the last few weeks during testing.

There was nothing in particular that gave us a hard time, Koenigsmann told reporters Wednesday during the Federal Aviation Administrations 20th Annual Commercial Space Transportation Conference in Washington. Its more like this whole thing was a huge effort, and at the end of it you want to test and test things again to make sure that theyre ready to go.

SpaceX resumed launches Jan. 14 with a successful Falcon 9 mission from Vandenberg Air Force Base in California, but the companys return-to-flight in Florida has been paced by the construction at pad 39A.

NASA launched 12 Saturn 5 rockets from pad 39A during the Apollo moon program including Apollo 11 and 82 shuttle flights departed from the seaside launch complex.

But NASA decided it no longer needed pad 39A after the shuttles retirement. Nearby launch pad 39B, previously built for Apollo and shuttle flights, will be home to NASAs Space Launch System, a government-owned heavy-lift rocket that will launch astronaut crews on deep space expeditions.

The concrete foundation of pad 39A dates back to the Apollo era of the 1960s, while the 347-foot-tall (106-meter) fixed service structure and lightning tower were emplaced before the first shuttle launch.

It gives me a little bit of chills when I walk out there and see stuff thats left over from Apollo, Koenigsmann said.

Since SpaceX took over, changes to pad 39A have included the construction of the new rocket hangar outside the south gate to the facility, where space shuttles and Saturn 5 moon rockets arrived on top of tracked crawler-transporters after rollout from the nearby Vehicle Assembly Building.

The hangar can accommodate five Falcon 9 rocket cores at a time, according to SpaceX.

Other additions include the installation of RP-1 kerosene fuel tanks and the construction of the massive transporter-erector, which is sized to accommodate SpaceXs powerful triple-body Falcon Heavy rocket when it debuts later this year.

The transporter-erector is big enough to do Falcon Heavy. We can launch Falcon 9 with it in the center, of course, but the Falcon Heavy drives the size of it, Koenigsmann said. You can see Its bigger than the one we used to have.

The facilitys water system has also been refurbished to provide acoustic and heat protection to the pad deck during liftoffs, and the water tower at the northeast perimeter of the pad has been repainted, now emblazoned with the SpaceX logo.

Later this year, SpaceX plans to add an access arm to pad 39As fixed service structure for astronaut crews to board a human-rated version of the Dragon spacecraft beginning in 2018. SpaceX and Boeing have contracts with NASA to develop commercial spaceships to rotate crews between Earth and the space station.

SpaceX officials intend to base crewed launches and Falcon Heavy missions from pad 39A, and flights for the U.S. military and some commercial missions will be launched from pad 40 a few miles to the south.

Pad 40 should be ready for launches again in a few months after ground teams finish clean-up and repairs following the explosion of a Falcon 9 booster there in September.

SpaceX said the construction crew working at pad 39A will move over to pad 40 in the coming weeks. A firm timetable for pad 40s availability for launches will be better known once repairs begin, but the facility could be ready by the middle of the year, officials said.

SpaceX aims to launch once every two weeks after pad 39A is inaugurated later this month, continuing with the deployment of an EchoStar communications satellite in early March, then the launch of an SES telecom payload aboard a previously-flown first stage booster later in March.

With its Launch Readiness Review complete, Arianespace continues to make preparations to launch itsfirst Ariane 5 rocket of 2017. The delivery into space of two communication satellites,SKY Brasil-1 and Telkom 3S, is scheduled for the beginning of an 86-minute launch window that opens at 4:39 p.m. EST (21:39 GMT) on Feb. 14, 2017.

The mission, designated VA235, is being flown todeliver the two satellites to geosynchronous transfer orbit (GTO). The European heavy-lift vehicle is notable in its capability to deliver multiple, large satellites into orbit, allowing customers to share launch costs.

The 13,228-pound (6,000-kilogram) AT&T/DirecTV SKY Brasil-1 spacecraft will supply digital entertainment services to Brazil via DirecTVs Latin America subsidiary.

Sharing the ride to GTO inside the fairing will be the 7,826-pound (3,550-kilogram) Telkom 3S digital services satellite.

The state-owned Telkom Indonesia satellite will provide telecommunications and high-definition television services throughout the island nation.

Riding in the lower bay of the two-position SYLDApayload carrier is the Telkom 3S satellite. The third Telkom satellite to be launched by Arianespace, it was built on the Thales Alenia Space Spacebus 4000B2 platform and is outfitted with 24 C-band, eightextended C-band, and 10 Ku-band transponders.

Telkom 3S will ultimately be positioned at 118 degrees Eastand will provide a multitude of digital services to customers in Indonesia, Malaysia, and Southeast Asia. The medium-class satellite has twin solar arrays, providing the necessary6.3 kilowatts of payload power, and has an expected on-orbit lifetime of 15 years.

The other satellite, SKY Brasil-1, will sit in SYLDAs top position. Alternately known as Intelsat 32e, the satellite was built on the Airbus Defense and Space Eurostar E3000 spacecraft architecture, a widely used and flexible satellite bus.

Using its60 Ku-band transponders, the satellite will provide servicesto Brazil and areas of the North Atlantic Ocean. After settlinginto its orbital slot at 43.1 degrees West, SKY Brasil-1 is expected to deliver digitalcontent for at least 19 years.

Arianespaces reliable Ariane 5 rocketwill be delivering the satellite duoto GTO. It is configured in its ECA arrangement for flight VA235. The heavy-lift rocket has been a mainstay of the multinational launch providerand offers a high degree of precisionwith its ability to place payloads into orbit with near meter-level accuracy.

Like NASAs now-retired Space Shuttle, the Ariane 5 makes use ofsolid-fueled boosters to supplement the mainliquid-fueled engine.

A pair of P241 solid rocket boosters will provide a combined 3.18 million pounds (14,160 kilonewtons) of thrust at liftoff. Each will burn for approximately 130 seconds, providing roughly 92 percent of the Ariane 5s liftoff thrust. Once their propellant is consumed, they will separate and fall into the Atlantic Ocean.

Supplying the remaining eightpercent of liftoff power is the core stages Vulcain 2 cryogenic engine. Burning a mixture of liquid hydrogen and liquid oxygen, the hydrolox powerplant provides 220,000 pounds (960 kilonewtons) of sea-level thrust. That increases to 310,000 pounds (1,390 kilonewtons) as it climbs into the vacuum of space.

The second stage is outfitted with a single HM7B cryogenic engine. Itsupplies 15,000 pounds (67 kilonewtons) of vacuum thrustand can operate for 945 seconds.

The mission will be broadcast live via Arianespaceswebsite. Coverage will begin 15 minutes beforethe scheduled liftoff.

Teams practice for Cape Canaveral’s first launch of Minotaur 4 … – Spaceflight Now

CAPE CANAVERAL Three inert Peacekeeper missile stages have been stacked at Cape Canaverals Complex 46 pad, demonstrating the techniques that will be used to assemble a Minotaur 4 rocket to launch an experimental space surveillance satellite this summer.

Decommissioned Peacekeeper missiles form the basis for Minotaur 4 rockets, operated by Orbital ATK, and will deliver the majority of power to launch a small spacecraft, called SensorSat, into Earth orbit.

Launch is tentatively planned for July 15 at roughly 1 a.m. EDT (0500 GMT).

Known as the Operationally Responsive Space-5 mission, or ORS-5, it will be the first Minotaur launch from Cape Canaveral.

Officials say the Cape was chosen as the launch site because it is best suited to fly the special five-stage Minotaur 4 into the desired equatorial orbit.

The payload will circle the planet in low-Earth orbit to scan the valuable region of space 22,300 miles high the geosynchronous orbital belt to spot debris and warn against collisions.

Geosynchronous orbit is where communications satellites, weather observatories and key reconnaissance platforms reside because that altitude allows the craft to fly continuously above the same part of the globe.

Many of the details about ORS-5 remain classified. But SensorSat will test technologies and reduce the risk for future space situational awareness missions.

The launch pad hosting this mission is Complex 46, a former Trident missile test site built in the 1980s for the U.S. Navy, then converted to spaceflight users in the 1990s and employed by Lockheed Martin to launch two Athena boosters including NASAs Lunar Prospector.

Space Florida, an arm of the state, now oversees the complex for commercial customers. It will be the first launch from the pad, which is on the easternmost tip of the Cape, in 18 years.

Five previous Minotaur 4 rockets have launched from Kodiak Island in Alaska and Vandenberg Air Force Base in California since 2010.

The entire Minotaur family has conducted 25 missions since 2000, all successfully. Cape Canaveral will join Kodiak Island, Vandenberg and Wallops Island in Virginia as sites that have hosted launches.

Mission planners selected the Cape to launch SensorSat due to the plane change required en route to achieve the targeted 375-mile-high circular orbit at 0 degrees inclination. A Wallops-based launch could not reach such an orbit with Minotaur 4, officials said.

The successful pathfinder operations at Complex 46 were completed Sunday and punctuated with a photo op for the news media. The inert stages will be destacked beginning Monday.

The real rocket for ORS-5 will be stacked beginning about three weeks before launch. That will be followed by a week-and-a-half of pre-flight testing.

Minotaur 4 will blast off on 500,000 pounds of thrust, propelling the 193,000-pound, 78-foot-tall rocket on a half-hour trip to orbit.

After the three Peacekeeper motors burn, two commercial upper stages deliver the final pushes to reach orbital velocity and then change planes to obtain the correct inclination for ORS-5.

MRO data utilized for Mars 2020 landing-site selection – SpaceFlight Insider

Paul Knightly

As scientists and engineers from around the world have gathered this week to discuss potential landing sites for NASAs Mars 2020 rover, a key piece of hardware has been central in aiding their efforts. The Mars Reconnaissance Orbiter (MRO) arrived at Mars in 2006 and has been capturing high-resolution imagery and data about the Martian surface in the 11 years since. This data is now being used to aid in landing-site selection efforts for the Mars 2020 rover and other future missions.

While the meeting this week discussing potential landing sites for the Mars 2020 rover focused on eight candidate landing sites, MRO data has also been used to evaluate the landing sites for past robotic missions, including Phoenix and Curiosity. The data is even being used to evaluate some 45 potential exploration zones for future crewed missions.

From the point of view of evaluating potential landing sites, the Mars Reconnaissance Orbiter is the perfect spacecraft for getting all the information needed, said the workshops co-chair, Matt Golombek of NASAs Jet Propulsion Laboratory (JPL). You just cant overstate the importance of MRO for landing-site selection.

The high-resolution of data returned by the MRO enables engineers and scientists to evaluate the safety of candidate landing sites. Stereoscopic 3-D images can reveal whether slopes are too steep and help to develop terrain models that can aid in future rover operations. MRO data can also reveal the distribution of mineral deposits that are important to achieving mission objectives. These terrain and mineral models are already being used by the Curiosity and Opportunity rover teams to help plan driving routes for those rovers by guiding them to interesting targets while staying out of potentially dangerous situations.

Missions on the surface of Mars give you the close-up view, but what you see depends on where you land. MRO searches the globe for the best sites, said MRO Deputy Project Scientist Leslie Tamppari of JPL.

MRO also serves as a communications relay for present surface missions in tandem with other orbiting spacecraft. Scientists and engineers plan to utilize these communications relay capabilities to support the Mars 2020 rover. This month, it will reach and surpass the milestone of 6,000 relay sessions for Mars surface missions.

While MRO data is important to characterizing potential landing sites, the orbiter has done much more than just assisting with Martian surface operations. MRO has acquired more than 224,000 images and millions of other observations of Mars during its nearly 50,000 orbits of the planet. This large volume of data returned will surpass 300 terabyteslater this month, which is more data than has been returned from any past or present interplanetary mission combined. For perspective, that is more data than would be contained in four months of non-stop high-definition video.

Whether it is looking at the surface, the subsurface or the atmosphere of the planet, MRO has viewed Mars from orbit with unprecedented spatial resolution, and that produces huge volumes of data, said MRO Project Scientist Rich Zurek of JPL.These data are a treasure trove for the whole Mars scientific community to study as we seek to answer a broad range of questions about the evolving habitability, geology and climate of Mars.

Among the other discoveries made possible by data returned by MRO are the following:

The High Resolution Imaging Science Experiment (HiRISE) camera on the orbiter took the four images used in this animated sequence, showing the same site over the time period from March 31, 2007, to April 2, 2012. The earliest of the four observations is the one in which the impact blast zone looks darkest. The space-rock impact that created this blast zone occurred sometime between September 2005 and February 2006, as bracketed by observations made with the Mars Orbiter Camera on NASAs Mars Global Surveyor spacecraft. The location is between two large volcanoes, named Ascraeus Mons and Pavonis Mons, in a dusty area of the Tharsis region of Mars. During the period from 2007 to 2012, winds blowing through the pass between the volcanoes darkened some regions and brightened others, probably by removing and depositing dust. The view covers an area about 1.0 mile (1.6 km) across, at 7 North latitude, 248 East longitude. North is toward the top. GIF & Caption Credit: NASA/JPL-Caltech/Univ. of Arizona

Commercial spaceflight sector receiving 10m UK government boost – Market Business News

Her Majestys government plans to make 10 million of commercial spaceflight funding available to projects that will launch people and satellites into space from the United Kingdom. It is also introducing new legislation to regulate commercial spaceflight by 2020.

In a recent announcement about the plans, universities and science minister Jo Johnson says:

Spaceflight offers the UK the opportunity to build on our strengths in science, research and innovation. It provides opportunities to expand into new markets, creating highly-skilled jobs and boosting local economies across the country.

The UK government is inviting businesses developing spaceports and technology for operating commercial spaceflights to apply for funding assistance. Image is of United Kingdom seen from Sentinel-3A satellite Credit: ESA

Commercial spaceflight market 25 billion

Johnson says the commercial spaceflight market is estimated to be worth around 25 billion over the next 20 years and the governments ambition is for the UK to have 10 percent of the market by 2030.

Businesses developing spaceports and technology for operating commercial spaceflights are invited to submit proposals to access the funding.

In its call for proposals, the government says the aim is to make the UK the first country in Europe where operators can launch, horizontally or vertically, small satellites into orbit or sub-orbital flights for science and tourism.

Johnson says a dedicated Spaceflight Bill is also due to be published within the next few weeks.

Small satellite market growing

The global market for small satellites is developing rapidly. Clusters of hundreds of microsatellites are due to be launched over the next decade to provide telecommunications and enhanced imaging for a range of applications.

Plans at organizational, national and regional level are already forming to create the technology and low-cost services for putting these satellites into space.

For instance, 16 space agencies and universities from nine Asian countries including Japan recently formed an Asian microsatellite consortium.

Human spaceflight

Meanwhile, innovative companies are also working on affordable ways to put people into sub-orbital space whether for the purposes of scientific research, tourism, or high-speed travel.

One example is Virgin Galactic (VG), who recently carried out their first successful glide test of the VSS Unity, their first spaceship to be built in-house.

Eric Stallmer, president of the Commercial Spaceflight Federation says the flight, which was completed at Mojave Air & Spaceport in California in the United States, brings VG one step closer to their goal of making access to space frequent and safe.

The government has set up a webpage for news, announcements, and guidance on commercial spaceflight in the UK.

HOUSTON, Texas A model of NASAs Orion spacecraft is prominently placed within theSpace Vehicle Mockup Facility at NASAs Johnson Space Center. We sat down with Rick Mastracchio, a four-time spaceflight veteran with more than 227 days on orbit about how the Astronaut Office at JSC is working to make the agencys new Orion spacecraft more self-sufficient than those that preceded it.

NASAs Orion Assistant Manager for Integration, Annette Hasbrook, also spoke with SpaceFlight Insider about how NASA is developing not just technology, but protocols that are considered critical to send crews farther into space than has ever been attempted before. Photo Credit: Marisa Rhian / SpaceFlight Insider

At present, NASA is working to have Orion conduct its second flight in late 2018 (the spacecrafts first mission, Exploration Flight Test 1, launched on Dec. 5, 2014). The upcoming flight, Exploration Mission 1, will be the first for NASAs new super-heavy-lift rocket, the Space Launch System.

NASA and its family of contractors arent content with reinventing the wheel, they are looking to develop new, more self-sufficient systems which should be able to handle problems that crews have not had to face in more than four decades.

We havent left low-Earth orbit since 1972, the last Apollo mission, so thats a big change, Mastracchio told SpaceFlight Insider. Some of the changes that I foresee is that were going to have probably a much smarter vehicle than what we had on Space Shuttle or Soyuz, or on the Space Station in terms of it will be more autonomous.

Autonomous was one word that was repeatedly used to describe how Mission Control, also located at JSC, and the crew will need to be as missions travel farther and farther away from our home world.

Mastracchio noted that, as these missions get underway, the Mission Controls role will decrease as crews venture to possible destinations such as Earths moon, an asteroid, and Mars.

Mastracchio and Hasbrook spoke with SpaceFlight Insider for the better part of an hour. They informed SFI regarding contingency scenarios that were under development as well as about how astronauts are being trained to broaden their already diverse array of talents to support deep space missions and more.

Upcoming SLS/Orion flights include the first integrated flight of the launch vehicle and spacecraft, EM-1, as well as the first crewed flight (Exploration Mission 2) and the Asteroid Redirect Mission, which, according to Jeff Foust at Space News, if funded, could fly in late 2021.

SpaceX readies rocket for tests at historic pad 39A – Spaceflight Now

SpaceX engineers are preparing to mount a Falcon 9 rocket at Kennedy Space Centers historic launch pad 39A for the first time this week as the company declares the modified facility ready to support a new era of commercial space missions.

The two-stage rocket, without its payload, could roll out of SpaceXs hangar at the southern perimeter of pad 39A and up the ramp to the launch mount as soon as Thursday.

SpaceX aims to fill the rocket with super-chilled kerosene and liquid oxygen propellants Friday if everything goes according to plan for a hotfire test of the Falcon 9s first stage engines. The nine Merlin 1D powerplants will fire and power up to 1.7 million pounds of thrust for several seconds, sending a plume of exhaust out of pad 39As redesigned flame trench.

Sensors in each engine will measure many performance parameters during the brief ignition at the launch pad. Hold-down restraints will keep the rocket on the ground.

SpaceX is prepping the rocket for a launch targeted for around 10:01 a.m. EST (1501 GMT) on Feb. 18 with a Dragon cargo craft flying to the International Space Station. The commercial supply ship is slated to carry 5,266 pounds (2,389 kilograms) of equipment and experiments to the orbiting laboratory.

The crucial static fire test will double as a check of the rockets readiness for flight and the function of the launch pads fueling, telemetry and water deluge systems, all of which were overhauled by SpaceX in recent months.

Once the test is complete, ground crews will lower the rocket and attach the Dragon cargo freighter for launch next weekend.

Hans Koenigsmann, SpaceXs vice president of flight reliability, said Wednesday that testing of the new ground systems at 39A was nearly complete, allowing managers to move ahead with rollout of the rocket.

This is a huge pad, Koenigsmann said. The runs from the LOX (liquid oxygen) farm and the fuel farm down to the launch head are huge. The transporter-erector is huge. Its like one-and-a-half million pounds of steel, and (it has) so much technology because this thing controls all the interfaces (with the rocket).

The transporter-erector will carry rockets from the hangar up the incline to the pad, then lift the vehicles vertical. The rocket carrier was observed vertical at pad 39A in the last few weeks, and on Wednesday it was seen moving back toward the hangar, where the Falcon 9 rocket sits awaiting the static fire.

There was nothingin particular that gave us a hard time, Koenigsmann told reporters Wednesday during the Federal Aviation Administrations 20thAnnualCommercial SpaceTransportationConference in Washington. Its more like this whole thing was a huge effort, and at the end of it you want to test and test things again to make sure that theyre ready to go.

The last time a rocket stood at pad 39A was in July 2011, when the space shuttle Atlantis lifted off on the final flight of NASAs iconic winged spaceships. SpaceX signed a 20-year lease for the launch complex from NASA in 2014, and preparations at pad 39A took on a feverish pace last year after the companys other launch facility at Cape Canaveral sustained major damage when a rocket exploded.

SpaceX officials intend to base crewed launches and Falcon Heavy missions from pad 39A, and flights for the U.S. military and some commercial missions will be launched from pad 40 a few miles to the south.

Pad 40, which lies on U.S. Air Force property, should be ready for launches again in a few months after ground teams finish clean-up and repairs following the catastrophic explosion of a Falcon 9 booster there in September.

The rocket was destroyed during the final countdown before a static fire test Sept. 1, along with an Israeli-owned communications satellite.

SpaceX said the construction crew working at pad 39A will move over to pad 40 in the coming weeks. A firm timetable for pad 40s availability for launches will be better known once repairs begin, but the facility could be ready by the middle of the year, officials said.

SpaceX aims to launch once every two weeks after pad 39A is inaugurated later this month, continuing with the deployment of an EchoStar communications satellite in early March, then the launch of an SES telecom payload aboard a previously-flown first stage booster later in March.

NASAs Michoud Assembly Facility (MAF) was the site of a confirmed tornado strike at 11:25 a.m. CST (12:25 p.m. EST / 17:25 GMT). So far, only minor injuries have been reported, and NASA is accounting for all of its personnel and contractors as well as assessing thedamage caused by the storm.

Meanwhile, officials are continuing to monitor the weather and the agencys emergency response team is assessing just how much damage the storm inflicted on the nearly 80-year-old facility.

As of this writing, it is unclear what, if any, damage might have been done to the rockets that are currently under development (the first of these is being prepared for Exploration Mission 1, currently slated to take place in late 2018). NASA has prioritized the assessment to Bldg 103so that the environmental controls of the Space Launch System and Orion can be maintained.

The MAF was used during World War II for the construction of C-76 cargo planes. During the Korean War, it was used to construct engines for Sherman and Patton tanks. Then, in 1961, NASA took over control of the facility.

During the Space Shuttle Program, the MAF was where the large, rust-colored External Tanks that the orbiter used on its 135 missions were produced.

UPDATE: According to an internal NASA memo an estimated 40 to 50 percent of the buildings at Michoud received some level of damage, with five buildings receiving severe damage. Building 350, which houses the USDA National Finance Center, had the largest amount of damage. Power was restored to Michouds substation last night (Feb. 7, morning of Feb. 8).

NASA issued the following statement via a press release issued on Feb. 8:

Michoud remains closed to all but security and emergency operations crews. Temporary flight restrictions are in place over the area to ensure recovery and operations crews can complete their work without interference from other drones or low-flying aircraft. All Michoud personnel are accounted for, and no new injuries have been reported.

The entire NASA family pulls together during good times and bad, and the teams at the Michoud Assembly Facility are working diligently to recover from the severe weather that swept through New Orleans Tuesday and damaged the facility, said acting NASA Administrator Robert Lightfoot. We are thankful for the safety of all the NASA employees and workers of onsite tenant organizations, and we are inspired by the resilience of Michoud as we continue to assess the facilitys status.

Is 2017 the year human spaceflight returns? – Deutsche Welle

To call it a space race at this stage would be odd, not to mention misleading. What we're seeing now is more like a sprint, or a dash, where all the competitors are holding hands to the finish.

First, both the Europeans and Americans are keen on human spaceflight. And they know they can't do it alone - nations are pooling resources as much with each other as they are with commercial space enterprises. So much is clear. And as a result it will be a European Service Module that propels NASA's Orion spacecraft beyond the moon and back in 2018.

But there are further plans to build a second module for another mission, possibly in 2021, that will carry astronauts. If this happens, and no other mob trumps it, the mission will be the first to take humans beyond low orbit since 1972. The mission will be powered by European hardware. It will provide water, thermal control and atmosphere for a crew of up to four astronauts.

Next week, the European Space Agency and Airbus Defence and Space sign off on an agreement with NASA, and they will get things started.

The community, even in Europe, has embraced a public-private approach to space.

"Involving the commercial sector and their new fresh ideas, of course it's a good idea," says David Parker, ESA's head of Human Spaceflight and Robotic Exploration. "There are fantastic entrepreneurs out there who may provide a telecommunications service around the moon so that everybody can have the telecommunications for their lunar lander or their astronauts."

Modern launch pad

Then there's SpaceX, one of the commercial providers that has been delivering supplies to the International Space Station. It plans to inaugurate a revamped, fourth launch facility - a modified NASA launch complex in Florida known as "39A" - also next week.

ESA's David Parker used to head the UK Space Agency. The UK has long focused on the commercial benefits of space

NASA's Space Shuttles launched from 39A (before they were grounded). They were the last of America's human space capability.

Activating 39A may well help SpaceX clear a current backlog of about 70 flights.

It's also another step in NASA's plans to have SpaceX and Airbus competitor, Boeing, ferry astronauts to the International Space Stationby the end of 2017. The SpaceX rocket, Falcon 9, which carries a Dragon capsule, launches from 39A. Boeing has its CST-100 spacecraft.

All this commercial enterprise will, however, come at a cost.

"Of course it will be a commercial service, but bringing that kind of entrepreneurial spirit, I don't think it's a bad thing," says Parker.

For science and riches

Historically, says Parker, people have explored for various reasons. During the gold rushes of the Wild West and Australia, for instance, some will have gone for the riches and others for the pure exploration, the science.

But space is such an untapped resource, there's so much we don't know,what it is, how it "functions," or how much it's worth. So are we really prepared to let this rejuvenated age of entrepreneurial space exploration develop on a "wait-and-see" basis? Just look at the internet if you're wondering where that kind of attitude may lead us.

That said, skeptics like me may have to endure a few entrepreneurs earning bucket loads in the short-term, and hang on for the long-term benefits for the rest of humanity.

Economics Minister Brigitte Zypries shares a mobile moment with astronaut Matthias Maurer and ESA chief Jan Wrner

"When we understand the other 90 percent of the physics, imagine what relevance that might have to everyday life," says Parker. "Just as you rely on a mobile telephone today, you don't think about electromagnetic wave theory, do you? But fundamental physics is built into your phone."

Equal opportunities?

So finally what about our investment in people as we take this next step? We talk about "manned" missions to the moon. But does that include women? Germany's Economics Minister Brigitte Zypries, whose department is responsible for space activity, certainly hopes so.

"A lot of women are interested," says Zypries. "About 900 women applied through the initiative, "Die Astronautin [The astronauts]." They're working with ESA and we'll find out soon who's among the final 10 candidates. So, first, let's select one or two of them. But we also have to make sure women continue to be interested in technical professions, and we can only encourage them by saying, 'Get stuck in, you can do it.'"

David Parker can do little but agree. And he sees the number of opportunities for people getting to space, wherever or whatever they are, as commercial and public human spaceflight takes off.

"With the Americans building not one, not two, but three new space vehicles that will take astronauts into space, up to the space station, and also beyond as we look to heading back to the moon and onto Mars, the opportunities are going to increase," says Parker. "And there will be different ways for people to get up into space, maybe even commercially. The more people that experience going to space the better."

KENNEDY SPACE CENTER, Fla. The launch of aSpaceXFalcon 9 rocket with NASAsCargo Resupply Services10 (CRS-10) mission is now targeted forFeb. 18. The launch of the cargo variant of SpaceXs Dragon spacecraft is expected to mark the rebirth ofone of KSCs most iconic launch sites LC-39A.

Some 4,473 pounds (2,029 kilograms) of pressurized and 2,154 pounds (977 kilograms) of unpressurized cargo will be aboard the CRS-10 Dragon capsule bound forthe International Space Station (ISS). It will take to the skies during an instantaneous (one second long) launch window.

While any number of factors could have caused the launch to be set for this date, a report appearing on Universe Today suggestsit was due to the mission having not receivedits Federal Aviation Administration (FAA) license.

Previously, on Jan. 30, the NewSpace companydecidedto change the order of its launch manifest to move CRS-10 before to the launch of the EchoStar 23 communications satellite.

A SpaceX statement stated: This schedule change allows time for additional testing of ground systems ahead of the CRS-10 Mission The launch vehicles, Dragon, and the EchoStar satellite are all healthy and prepared for launch.

This will be thefirst launch from LC-39A since the final Space Shuttle mission, STS-135, in July 2011. In 2014, the NewSpace firm signed a 20-year lease on the complex. Since then, it has been modifying it to be able to process and launch Falcon 9 and Falcon Heavy rockets.

Changes to LC-39A include the addition of a horizontal integration facility (HIF), a rail system to carry rockets from the HIF to the pad, and a Transporter Erector (TE) attached to the top of the pad.

CRS-10 will also mark SpaceXs first launch from the East Coast since the Sept. 1, 2016,launch pad explosionat Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station just south of Kennedy Space Center. That accident saw the complete loss of the Falcon 9 launch vehicle, the $195 million Amos 6 satellite, and the destruction of much of the launch service equipment at SLC-40.

SpaceFlight Insider reached out to both NASA and SpaceX in order to confirm the new launch date. SpaceX responded with the following: Our current guidance is NET mid-February. Before that, it was NET February [].

On Feb. 8, 2017, the Center for the Advancement of Science in Space (CASIS) held a teleconference, during which it was stated that the launch would take place on Friday, Feb. 17. Shortly thereafter, SpaceX issued a tweet stating that they were targeting Feb. 18.

Spaceflight Changes the Shape of Astronauts’ Brains – Space.com

The International Space Station (ISS), photographed by an astronaut aboard the space shuttle Endeavour on Feb. 10, 2010. Astronauts who flew on ISS and space shuttle missions experienced changes in brain volume, a new study has found.

It appears that spaceflight really goes to astronauts' heads.

Doctors and scientists have long known that exposure to a weightless environment causes muscles to atrophy, bones to weaken and vision to deteriorate, among other effects. Now, a new study has determined that spaceflight also causes some parts of the brain to expand and others to contract. [The Human Body in Space: 6 Wild Facts]

"We found large regions of gray-matter volume decreases, which could be related to redistribution of cerebrospinal fluid in space," study principal investigator Rachael Seidler, a professor of kinesiology and psychology at the University of Michigan, said in a statement.

"Gravity is not available to pull fluids down in the body, resulting in so-called puffy face in space," Seidler added. "This may result in a shift of brain position or compression."

Seidler and her team studied magnetic resonance imaging (MRI) scans of 26 astronauts 12 who flew on two-week-long space shuttle missions, and 14 others who lived aboard the International Space Station (ISS) for five to six months.

These MRI scans are the first images ever to show how spaceflight changes brain structure in humans. Blue shows areas of gray-matter volume decrease, likely reflecting shifting of cerebrospinal fluid. Orange shows regions of gray-matter volume increase, in the regions that control movement of the legs.

The brain regions that expanded are associated with the control of leg movement and the processing of sensory information from the lower body, team members said. Therefore, the MRIs are likely capturing the brain learning a new skill how to move in microgravity and doing so around the clock, Seidler said.

"It's interesting, because even if you love something, you won't practice more than an hour a day," she said. "In space, it's an extreme example of neuroplasticity in the brain, because you're in a microgravity environment 24 hours a day."

It's unclear how long these changes last after astronauts come back to Earth, or how the shifts may affect cognitive ability, the researchers said. Seidler and her team are currently conducting another long-term study to look into these questions.

The new study was published in December 2016 in the journal Nature Microgravity. The lead author is Vincent Koppelmans, of the University of Michigan's School of Kinesiology.

Goals for NASA’s proposed Europa Lander begin to crystallize – SpaceFlight Insider

Members of a NASA Science Definition Team (SDT) recently completed a report on the science value for a proposed Europa landerand gave design recommendations for the notional explorer. The search for evidence life on the icy moon is near the top of the list.

Scientists believe Europa has an active subsurface ocean, warmed by tidal heating, and enriched by compounds created from the constant bombardment of the icy crust by charged particles streaming from Jupiter. (Click to enlarge) Image credit: NASA

Though Europa is much further from the Sun than is Earth more than 483 millionmiles (777 million kilometers), compared to 93 million miles (150 million kilometers) for Earth scientists have long hypothesized that the icy moon harbors a liquid water ocean beneath its frozen crust.

The presence of liquid water is considered to be an essential ingredient for the evolution of living organisms, and Europa may have twice as muchwater beneath its crust than all of Earths oceans combined.

This liquid environmentmay be enrichedwith chemical compounds created by the bombardment of Europas surface by particles streaming from Jupiters intense magnetic fields, thereby providingan energy source upon which organisms could thrive.

With the ocean likely being in contact with a rocky surface deep within the moon, the three key ingredients water, energy, and organic compounds upon which life is built may be in abundance on the Jovian satellite.

The fundamental goal of the mission would be to look for the direct evidence of life on Europa.

The SDT was given the responsibilityto develop a series of criteria to be used to determine if life had, indeed, been found. To this end, the teammade recommendationson the type and quantity of science instruments to be carried on the lander to accomplish this task.

However, looking for life wont be the landers soleobjective.

Scientists and engineers expect there will be subsequent missions to Europa, so the lander will be designed to gather as much dataabout the icy moon, and its subsurface ocean, as possible. This information will greatly benefit future missions to Europa, perhaps leading to an exploration of the moons subsurface ocean.

Though the destination may bethe same, the Europa Lander is an entirely separate mission from the larger mission to the Jovian system. Popularlycalled the Europa Clipper, the orbiterwill carry out a detailed exploration of its namesake moon as it orbits Jupiter once every 45 days.

Data gathered from that mission, tentatively scheduled for the early 2020s, will help scientists and engineers fine-tune the mission for the lander. The radiation-hardened orbiter will make a pass of Europaevery two weeks, many of which will be close flybys of the moon.

The lander, though, is still very much in its early design phase. NASA will hold two town hall meetings to discuss the SDTs reportand will assess the feedback from thescience community.
